21. Apply liquid gasket to the cylinder block mating sur_face of the oil pump.
NOTE:
. Use liquid gasket, Part No.08718 - oOOj or 08718- 0003.. Check that the mating surfaces are clean and drybefore applying liquid gaskel. Apply liquid gasket evenly, in a narrow bead cen-tered on the mating surface.o To prevent leakage of oil, apply liquid gasket tothe inner threads of the bolt holes.. Do not install the parts if five mtnures or morehave elapsed since applying liquid gasket.Instead. reapply liquid gasket after removing theold residue.
